To all to]; am it may concern.-

Be it known that I,'HORACE E. DELL, a citizen of United States, residing at Spring he, in the county of Ottawa, State of have invented certain new and do hereby declare the followingto be a full, such as will enable others skilled in thefart to which it appertains to make and use the same. i v 1 :The present invention is directed to new and useful improvements inincubators.

constructing'the device that the air therein will be kept moist. A further object of the invention resides in ,the provision of molstemng means whlch may be regulated so as tobe edective in cubator or all of the compartments, as desired. V

With these and other objects in view, this invention resides-in the novel features of construction, formation, combination and arrangement of parts to, be h more fully described, claimed and illustrated in the accompanying drawing, in whichz- Figure 1 is a top plan view of the device. Fig. 2 is a side elevation. Fig 3 is-an end view. Fig; 4 is a view of the-opposite end. Fig. 5 is a sectional view on line 55 of Fig.

ig. 6 is a similar view on line 6-6 of Fig. 1. Fig. 7 is a similar view on line 7-7 5 of Fig. 1.

The body 1 is dividedinto compartments 2, preferably four in number, said comin the posts 4.

The compartments 2 are arranged in pairs and spaced apart by the longitudinal chamher 5. which has one end opening at one of the ends of the body 1, the open end of said chamber being normally closed by the door 6.

Alined with the posts 4; are posts 7, which are provided with vertical grooves 8 which correspond with the simllar grooves 9 in the posts 4, said groovesbeing slidably en'ga ed by the doors 10 which are engaged by t e lower ends of the rods 11 saidrods being passed through the top 0 the body and terminate in ks 12, said hoo i hoohs being by the lower ends of clear, and exact description ofthe invention,

I the rods 13, which Patented July 6, 1915..

are passed through the supports 14 and have their threaded ends engaged by the nuts 15." As the nuts 15 bear against the supports 14 it is obvious that upon manipulation of said nuts the doors l0 may be raised or lowered, or may be adjusted to partially open positions so that the passage of Warm air may be regurom compartment to compartment. Eachcompartment 2 has its end walls provided with guide stray elevators 19. The top bars of the elevators are engaged by the lower ends of the screw rods 21, the upper ends of which project'above the top of the body 1 and are engaged by the .hand wheels 22 thusraising or lowering the tray elevators 19 so that the same may be adjusted inthe compartments 2 to subject the eggs in the trays 23 toi'diflerent degrees of heat, as desired.

The eggtrays 23 are slidably engaged in the guides 24 carried by the elevators 19,

said trays may be readily removed an replaced.

The sides of the compartments are provided with door openings 25, said openings being closed by the doors 26 which have their bottom edges hingedly connected to the sides of the body 1. 7 provided with glass panels 27, so that the process of incubation may be noted without opening the doors 26. To prevent light entering the compartments 2 each door is pro- 28, which are hingedly Mounted in the longitudinal chamber 5 are rollers 29 which support the trough 30 said trough being for the purpose of containing sand and water so that the proper moisture may be supplied to the compartments 2, it being of course understood that the-sliding doors 10 are adjusted to permit the warm air to circulate over the trough 30. The trough iszprovided with an eye 31 which is engaged by the hook 352 formed upon the handle 33, said handle. Matti conveniently mounted upon one end of the body 1, as shown in Fig. 4 of the wing. To remove the trough it is only necessary toremove the door 6 so that the handle can be with the eye 31 of said trough,

strips 16 which en-"j' gage the grooves 17 formed in the end bars 18 of th he doors 26 are lllld whereupon the same slid from the longitudinal chamber with' ease, as the same rests upon the rollers29.

The side walls of the body 1 are provided.

sa'attheir upper ends with. hingedly connected ventilating'doors 3 l,-which may be held in their o'pen'positions bythe hooks 35 which are connected to the side walls body, and as clearlysliowniii Fig. 4 of the drawing. j

a Supported upon-one end of the body 1 is a water tank 36, and passing through said the body '1 opposite the tank 36 and has leading therefrom a feedpipe- 44, which passes through. the bottom of the" body .1 and is directed upwardly, as at 45. The upwardly directed end of the pipe has attached thereto a rubber tube lti, which is provided I with .a nozzle 47 so that' the lamp maybe filled without removing the same from the receptacle f The nozzle i7 is; provided with a valve so that the supply of oil may be shut 0d and the nozzle placed 'on the bracket 48,,whichis fixed to one end of the body,

as clearly shown in Fig. 30f the drawing.

, "A heating coil 49 is arranged in the 1111- per .en'd of thebody 1 so that the same will 3 equally distribute the heat to the cOinpartQ 40 ments 2, said coil having its ends con nectedlto the tank 36 so that a constant cir- 'culationof water will be had in the coil, the j temperature of the water being regulated by [the disk valve 51 which ooacts with the tube 45 37, thus regulating the draftin. said tube,

'- as is the usual practice. The disk valve 51 is pivotally connected to' theloweriend of the rod 52, the upper end ofwhich 'is'similarly connected to one end of the lever 53,

meaevo said lever b ing pivot-ally supported by the so bracket pa mounted upon the upper part of the body 1.

Mounted in one of the compartments 2 is a thermostat 55, the actuating rodzeG thereof having its upper end-engaging the lever 53 so as the temperature varies in the compart- :ment the lever will be rocked to regulate the draft through the fine 37.. The thermostat 55 maybe of any standard construction as desire I The'body 1 is supported by the legs 57, which may be braced in any suitable manner.

To prevent the lamp from becoming extiniguished should the disk valve 51, close the'upper end of the fine 37, a reversely bent pipe 58 is'provided and extends through the body 1, and on a level with the coil 4.9, said pipe having one end connected to the upper end of the fine 37 and the other end bent upwardly, as at 59, so that a suflicient draft will be'had to keep the lamp burning.

W'hat'is claims is l. in an incubator, the combination with a, body, said body being divided into a pluralit'y of compartments, a longitudinal chamber separating the compartments into pairs, a moisture producing trough removably mounted in the chamber, and means for regulating the passage of moisture from the chamber to each compartment independently.

2. In an incubator, the combination with a body, said body being divided into compar'tments, a longitudinal chamber separating the compartments into pairs, a moisture trough removably mounted in the chamber, egg trays in the compartments, doors arranged between the opposing sides of the compartments, means for raising or lowering the doors to regulate the passage of moistened air from the chamber to the 001m partme'nts independently.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
